Product Introduction
High‑heat‑resistance O‑rings are high‑performance annular elastomer sealing elements for high‑temperature working‑conditions. Manufactured by precision compression vulcanization, available materials include FKM fluororubber, VMQ silicone, FFKM perfluoroelastomer and HNBR. Following ISO3601, AS568 international standards. They feature low compression‑set, excellent thermal‑aging resistance and stable elasticity under sustained high‑temperature environment. Working temperature varies by material:‑60℃‑220℃ for silicone,‑20℃‑250℃ for FKM, up to 320℃ for FFKM. Suitable for static and low‑speed dynamic sealing, preventing liquid and gas leakage under heat, oil and chemical medium. Widely applied in automobile engines, high‑temp hydraulic equipment, chemical valves, oven equipment and energy‑industry assemblies. Mass standard sizes are kept in stock. Custom inner‑outer dimension, cross‑section, hardness, color and OEM marking are supported per drawings or samples for high‑temperature equipment OEM and aftermarket replacement projects.
